Dear Mayor:

I'm a middle school student. I'm writing to tell you something aroud us. Nowadays, there are many left-behind children whose parents work away from their hometowns. Most of them are from the coutryside, you know, they have many problem. They are always lonely and stressed out because they are short of their parents' love. At the same time, they are easy to make mistakes even do some thing against the laws, because they're short of their families' care.

How to solve their problems? In my eyes, the government can set up a parents school for these children on holidays, you can organize" hand-in-hand" activity to call on more people to help them. You can also raise money to donate to these children. As the song says:"If everyone gives their love, the world will be better." It's very important for us to pay more attention to these children if we want to build a harmonious society.

Best wishes to you!

Sincerely, Li Hua

㈡ 求助,請高手幫忙翻譯一下下面的幾段文字

Over 20 years, scientist and the engineers start resolve Shanghai to sink to decline a problem, adopted restriction to pump water at that time of some measure, Shanghai strengthenned these measures in 2003.Request an each dozen an one mouthful a deep well, all want official permission.
Currently, mining groundwater the quantity has already had a control, the capacity of every year is 100,000,000 sign a square rice, pass these restrictions, city hall in Shanghai and related sections in the joint effort now.With decelerates the speed that Shanghai descends to sink further.
Because 20 centuries second half leaf to excessively open up of the land, big 興 the Anne 嶺's south forest edge has already retreated 200 kilometers at least, the big 興 is one of Chinese main LIN2 QUs, there is much waterfalls in its south region, very in keeping with farming.
In the past 50 years, a great deal of forest of this regions encounter to the breakage, is open up to become farmland, according to big 興 environmental protection the expert say, 200 kilometers of just retreat to distance in big 興 south of keep to calculate.
The big 興 LIN2 QU's area descend, cause the soil erosion and the river bed dried up, some places in Inner Mongolia, plant ever and thickly quilt, have already disappeared currently.A lot of rivers are already a year river often, now indeed decline the water but dried up because of lack.
In the past decade, Shanghai with equally sink to decline about 16 millimeters speed annually, with since 20's in 20 centuries, center city area in Shanghai about 600 district of the square kilometers have already equally descended to sink 2000 millimeter, some places even come to a 3000.
As early as 1921, the geologist discovers Shanghai is descending to sink, the expert thinks consistently, a main reason that sinks to decline is a groundwater to mine excessively, moreover, the fast increment of the city center skyscraper is also one of the reason that Shanghai sinks to decline.
Though this region forbids to open up in great quantities now, some farmers try to extend their farmland still, so forest still Be being eroded graally, the national forest management bureau will launch inquisition, looking up a responsibility person who result in now situation.
Pay attention to increasingly to the environment problem along with the international society, the environmental protection instry develops rapidly within the scope of world, the flourishing and national environmental protection instry increases annually 100 divide 6, but in East Asia with pulled this numeral of a little bit beautiful developing countries to then exceed 100 divide 10.
The environmental protection instry of China also in the booming development, since recent more than 10 years, the Chinese government promotes environmental protection strongly, in this kind of case, the environmental protection instry development is quick, having already become national economy an importance to constitute part.
The Chinese environmental protection instrial structure unbalance, the environmental protection service, the environmental protection proct, the market of[with] the environmental protection technique and the environmental protection funds needs a further development.The Chinese environmental protection instry contain huge potential, but have to adopt some measure to come to well exertive this kind of potential.
After big dam in Yangtse gorges starts retain water, fluid matter in Yangtze River has no occurrence variety.The wreath 衛 worker already from the water level river bed top clearance 1,990,000 ton garbages, 1,980,000 ton instrial waste, and 1500 ton dangerous odd-come-short, and carried on disinfection to 5,000,000 all toilets in the square meters.
The environment learns an estimate, fluid matter in Yangtse gorges still will keep national x-rated level, however start soar along with the reservoir water level after retain water, the water current speed reces slowly, river the by one's own sweep of the water ability will have to descend.Therefore, reservoir in Yangtse gorges still faces a huge challenge.
Decade in aftertime, China will invest about 400 憶 renminbis in the database area of Yangtse gorges, about 憶 US$48.The cent criticizes to build up 150 processing factories a processing factory with 170 city garbage, anticipate can handle this region 100 divide 85 above waste water and the garbages.
First stage, heavy celebrate to have already set up 19 dirty water processing factories with 13 garbage processing factories, they win of greatly part of will throw in movement before the reservoir water level soar to 135 meters.Locate the database area about 1000 severity pollution business enterprises to have already been close moreover

㈣ 納米材料在各個行業中的應用

(一)力學性質
高韌、高硬、高強是結構材料開發應用的經典主題。具有納米結構的材料強度與粒徑成反比。納米材料的位錯密度很低,位錯滑移和增殖符合Frank-Reed模型,其臨界位錯圈的直徑比納米晶粒粒徑還要大,增殖後位錯塞積的平均間距一般比晶粒大,所以納迷材料中位錯滑移和增殖不會發生,這就是納米晶強化效應。金屬陶瓷作為刀具材料已有50多年歷史,由於金屬陶瓷的混合燒結和晶粒粗大的原因其力學強度一直難以有大的提高。應用納米技術製成超細或納米晶粒材料時,其韌性、強度、硬度大幅提高,使其在難以加工材料刀具等領域占據了主導地位。使用納米技術製成的陶瓷、纖維廣泛地應用於航空、航天、航海、石油鑽探等惡劣環境下使用。
(二)磁學性質
當代計算機硬碟系統的磁記錄密度超過1.55Gb/cm2,在這情況下,感應法讀出磁頭和普通坡莫合金磁電阻磁頭的磁致電阻效應為3%,已不能滿足需要,而納米多層膜系統的巨磁電阻效應高達50%,可以用於信息存儲的磁電阻讀出磁頭,具有相當高的靈敏度和低噪音。目前巨磁電阻效應的讀出磁頭可將磁碟的記錄密度提高到1.71Gb/cm2。同時納米巨磁電阻材料的磁電阻與外磁場間存在近似線性的關系,所以也可以用作新型的磁感測材料。高分子復合納米材料對可見光具有良好的透射率,對可見光的吸收系數比傳統粗晶材料低得多,而且對紅外波段的吸收系數至少比傳統粗晶材料低3個數量級,磁性比FeBO3和FeF3透明體至少高1個數量級,從而在光磁系統、光磁材料中有著廣泛的應用。
(三)電學性質
由於晶界面上原子體積分數增大,納米材料的電阻高於同類粗晶材料,甚至發生尺寸誘導金屬——絕緣體轉變(SIMIT)。利用納米粒子的隧道量子效應和庫侖堵塞效應製成的納米電子器件具有超高速、超容量、超微型低能耗的特點,有可能在不久的將來全面取代目前的常規半導體器件。2001年用碳納米管製成的納米晶體管,表現出很好的晶體三極體放大特性。並根據低溫下碳納米管的三極體放大特性,成功研製出了室溫下的單電子晶體管。隨著單電子晶體管研究的深入進展,已經成功研製出由碳納米管組成的邏輯電路。
(四)熱學性質
納米材料的比熱和熱膨脹系數都大於同類粗晶材料和非晶體材料的值,這是由於界面原子排列較為混亂、原子密度低、界面原子耦合作用變弱的結果。因此在儲熱材料、納米復合材料的機械耦合性能應用方面有其廣泛的應用前景。例如Cr-Cr2O3顆粒膜對太陽光有強烈的吸收作用,從而有效地將太陽光能轉換為熱能。
